The Our Acidifying Ocean lab explores the chemistry of ocean acidification and its impacts on sea urchin larvae through interactive models, a virtual lab bench, and a microscope measurement tool. The primary aims of the lab are: Our virtual labs and activities serve many purposes. We have designed these open-access activities for individual, group, or classroom use. In many cases the virtual lab module will be most valuable if used in preparation for hands-on lab experience. Virtual labs may also serve as alternatives to lab experiences that may not be possible in the classroom setting because of limitations imposed due to time required for the actual lab, the expense of laboratory equipment, or safety. Our Lab Bench is designed to help students have a hands-on experience and is a part of several modules.
